IMPROVEMENT IN VAPOR-BURNERS.

Specification forming part of Letters Patent No. 86,870, dated February 9, 1869.

To all whom it may concern:

Be it known that I, HERRMAN S. SARoNI,

of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Vapor Burners and Heaters, of which the following is a full, clear, and exact description.

First. My invention consists in a novel method of combining a foraminous diaphragm, on the surface of which the vapor is burned, with a mixing-chamber, the walls of which extend above the diaphragm and are slit and bent over the diaphragm, by which means the walls of the mixing-chamber form a heat conductor or generator.

Second. My invention further consists in a novel method of combining, with a mixingchamber, foraminous diaphragms and tubular heat conductors or generators traversing the diaphragm, and communicating with the oilsupply below the valve which admits vapor to the mixing-chamber, which insures an effective generation of the vapor.

Third. The next part of my invention relates to the heater. Its object is to adapt the burner to heating buildings; and the improvement consists in a novel method of combining aforaminousburner with heating-flues,through which the products of combustion escape, and Y with a casin g or cylinder, through which air is drawn, after being heated by contact with the flues, and escapes into the apartment to be heated.

In the accompanying drawings, which make part of this specification, Figure 1 is a vertical section'through my improved apparatus, and Fig. 2 a similar view of a mixing-chamber having tubular conductors.

Petroleum or other analogous oil is fed from a reservoir, A, through a pipe, B, to a generator, G, where it is volatilized, and whence it escapes, in the form of vapor, into a mixingchamber, D, consisting, by preference, of an inverted frustum of a cone, open at each end, but divided transversely by three foraminous diaphragms, E F G. The lower diaphragm, E, extends across the bottom of the mixingchamber just below the inlet-valve or jet i.

As the vapor escapes into the lower compartment, E, air enters through the diaphragm E, and the air and vapor are thoroughly mingled in passing through the second diaphragm, F.

I The vapor is ignited above the third or upper diaphragm, G, and burns with a clear,

steady flame and great heat.

The wire-gauze of the diaphragm prevents the passage of the flame intothe mixing-chamber, and as its apertures are so numerous, the hissing noise which is so constant and attendant on this class of heaters is avoided.

The walls H of the chamber, which project above the upper diaphragm, are. slit, and

. the points thus formed bent in, so as to overhang the diaphragm. The heat impinges on these points, and is conducted down to the generator C by the walls of the mixing-chamber, which rests on arms connected with the generator.

To adapt this burner to warming buildings it is supported inside a perforated sheet-iron cylinder, J, supporting flues K. The hot air from the burner escapes up these hues and warms them. A drum, L, incloses these flues. The air enters this drum through an opening, I, at the bottom, and escapes at another opening, l, above.

The products of combustion escape through the pipe M.

In Fig. 2, I have shown an improved form of apparatus, in which tubes 0, communicatin g with the oil-supply tube at their lower endsand closed at their upper ends, rise through the diaphragms, and form additional generators and conductors, and increase the heat-developing capacity of the apparatus.

I am aware that wire-gauze screens have heretofore been used in combination with lamps to prevent explosions, and do not, therefore, broadly claim the use of a foraminous diaphragm.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with a foraminous diaphragm, on the surface of which the combustion is effected, of a mixing-chamber the walls of which are slit and bent over the diaphragm to form conductors, substantially as set forth.

2. The combination, with the mixing-chamber, of foraminous diaphragms and tubular conductors or generators traversing the diaphragms, and communicating with the oil-sup- HERRMAN s. SARONL Witnesses N.P. IGLEHART, J. I. PEYToN.
